In addition to its original intended use as a country code, and the secondary meaning as a type of company in German-speaking countries, the .ag domain has been marketed for use for agriculture-related sites, and for sites referencing the atomic symbol for silver, Ag. It also has a potential use for other domain hacks for English words that end in -ag. The Heritage Foundation uses .ag for URL shortening (herit.ag).

A German court (5. Zivilsenat des Oberlandesgerichtes Hamburg) ruled in July 2004 in second instance that a .ag domain may only be registered by an Aktiengesellschaft and more precisely by an AG that has the same name as the domain. That means that a company with shareholders in Germany with the name X AG, may not register y.ag.[1][2]
